What are the different viscometers available to measure viscosity?
Here are the six types we’ll cover: Orifice viscometers. Capillary viscometers. Falling piston viscometers.
What are the types of rotational viscometer?
Rotational viscometers such as Coaxial cylinders, concentric spheres, rotating disc, cone and plate, and coni-cylindrical, viscometers are commonly used in fields. Falling ball/piston viscometers together with rolling ball viscometers are also discussed.
What are the different types of viscosity?
- Dynamic Viscosity (Absolute Viscosity)
- Kinematic Viscosity.
What is viscometer and its types?
Three main types of viscometer are used: capillary tube (e.g., Ostwald), coaxial cylinder (e.g., Brookfield, Couette) and falling sphere (e.g., Hoeppler). For research, a sophisticated controlled stress rheometer such as a Carrimed or Bohlin may be used.
What is viscosity Slideshare?
1. Introduction • Viscosity is a quantitative measure of a fluid’s resistance to flow. • It is defined as the internal friction of fluid. • Lack of slipperiness is called as viscosity • Rheology: The study of the change in form and the flow of matter, embracing elasticity, viscosity, and plasticity.
What are the type of Redwood viscometers?
These instruments are for determining the viscosity of all oils, expressed in Redwood seconds at the temperatures of test as called for by IP 70. Both the types of viscometers, Redwood No. 1 and Redwood No. 2 electrical heating models are available.

What is difference between Redwood viscometer 1 and 2?
2. The jet orifice of redwood viscometer 1 has an internal diameter of 1.62mm and length of 10 mm. The jet orifice of redwood viscometer 2 has an internal diameter of 3.8 mm and length of 15mm. It is used to determine the viscosity of less viscous oils having flow (efflux) time less than 2000 second.
What is the difference between Redwood viscometer and Saybolt viscometer?
As the temperature rises the coefficient of viscosity decreases….Difference between Redwood and Saybolt Viscometer.
|Sr. No.||Saybolt Viscometer||Redwood Viscometer|
|2||A stopper is provided at the bottom of the tube for the liquid not to flow. It is released during the experiment.||The stopper is replaced with a ball valve and orifice.|
What is viscosity explain types?
Viscosity is a measure of a fluids propensity to flow. There are two kinds of viscosity commonly reported, kinematic and dynamic. Dynamic viscosity is the relationship between the shear stress and the shear rate in a fluid. The Kinematic viscosity is the relationship between viscous and inertial forces in a fluid.
